At least for the past year now I've had an issue where ESPN HD will break-up for my set top box that is upstairs. I have 3 STB's (one on each level). I haven't noticed the issue with any other box n the house, and I've tried every type of reset (including swapping boxes with the one downstairs). I can only assume that the tech split the signal too many times and there just isn't enough upstairs to keep all channels stable. Any ideas?
